What is the make and model of this A/C? You should be able to pull the ceiling grill off and see the data plate. Get back to me with this and I can assist you further. If the fan comes on, you know it has good AC power to it. It may be an issue with the start capacitor or control board or thermostat and we can run some tests to find out. Also, please give me the make and style of the thermostat..........analog slide control or digital. All follow ups are included in our fee. No time limit. I will make a phone chat option available for you as well.
Just checking back to see if you got this sorted out or do you still need more input from me?
I don't recall hearing that happening before........but, we see some strange things on this site. Thanks for getting back to me.
